500MW-1GW Annual Full Auto Solar Panel Production Line
500MW-1GW Annual Full Auto Solar Panel Production Line
Many customers want to open solar panel manufacturing factory, but they don’t know the manufacturing process and how to configure solar panel manufacturing machines so the idea has never been realized. Don't worry, I'd love to share with you.
1. Factory Layout Drawing
2. Mainly manufacturing process
Step 1: Test solar cell efficiency: make sure the same power cell to be used in one solar panel;
Step 2: Cut complete solar cell into small pieces;
Step 3: Welding solar cell: welding solar cell to string solar cell;
Step 4: Cutting EVA/TPT: according to the solar panel size to cut the EVA and TPT in the designed size;
Step 5: Lay up: achieve solar string automatic laying on glass EVA, and transporting module to the next process;
Step 6: Visual inspection: check the dirty for the Raw materials;
Step 7: Defect check: uses the EL tester machine to identifying micro-cracks, broken finger wires, and other invisible defects in solar modules;
Step 8: Lamination: after EL tester checking the defects, use solar panel Laminate the raw material into solar panel;
Step 9: Trimming: when the Solar panel get cooling after coming out from laminator, It need Cutting the edges, we call Trimming;
Step 10: Glue: use sealant to glue up on aluminum frame;
Step 11: Framing: use the framing machine to install the aluminum frame;
Step 12: Glue: fill the sealant to aluminum alloy after framing;
Step 13: Install junction box: glue the junction box and install it on the solar panel;
Step 14: IV Test: use solar simulator to test the finished solar panel Electrical performance test like power, current etc and record;
Step 15: Test the panel withstand voltage insulation;
Step 16: Defect check: uses the EL tester machine to identifying micro-cracks, broken finger wires and other invisible defects of finished solar modules;
Step 17: Label;
Step 18: Clean the surface and package.
3. Function & Picture of Main Machines of 500MW-1GW Annual Full Auto Solar Panel Production line
Solar Cell Laser Scribing Machine (no water no destructive)
Function:
No water no destructive solar cell laser scribing machine （called NDC） cuts solar cell into half piece or 1/3 piece，which can increase the output of the solar panel power.
NDC is with lower power, lower temperature, and water-free dicing, and also has higher bending strength, better electrical performance, and no secondary pollution or water-caused micro-broken after cutting.
Picture:
· MBB Solar Cell Tabber Stringer
Function:
MBB Solar Cell Tabber Stringer is used to weld the solar cells one by one through copper ribbon, and the cells are connected in series to form a string. The entire welding process is fully automated.
Picture:
· Automatic Solar Cell String Lay Up Machine
Function:
Achieving solar string automatic laying on glass EVA, and transporting module to the next process
Picture:
· Solar Strings Welding Bussing Machine
Function:
Adopt the method of separating the cell string from the glass, and grab the cell string in the air, then to interconnected solder the head, middle and tail bus bar of the middle wire edition module at a certain height; It has the function of a roll feeding bus bar, bending U and L leads upwards.
Picture:
· Automatic Solar Module EL Defect Tester
Function:
Used in testing the solar cell crack，breakage, black spot，mixed wafers，process defect，cold solder joint phenomenon.
Picture:
· Automatic Solar Panel Laminator
Function:
Automatic solar panel laminator is a mechanical device that presses multiple layers of materials together.
Picture:
· Automatic Solar Module Framing Machine
Function:
Automatic solar module framing machine is used to install the aluminum frame and automatically overflow glue.
Picture:
· Solar Module Sun Simulator
Function:
Solar module sun simulator is used to test the electric performance of Mono-Si or Poly-Si solar modules and record the results in files .
